We are looking for a Senior Finance Business Partner to join our newly established FP&A function and help transform financial planning and business decision-making across MGID. Working closely with business leaders, you will drive commercial insights, improve profitability and cash flow, and play a key role in implementing strategic financial initiatives, including a new prepayments policy.

Strategic Business Partnering & Commercial Governance

• Executive Co-Pilot: Serve as the primary commercial advisor to department heads (Publishing, Partnerships, Sales, Operations), translating complex financial realities into actionable strategic choices.
• Constructive Challenge: Actively evaluate business cases, hiring plans, and commercial assumptions. Ensure commercial decisions are backed by rigorous ROI data.
• Investment & ROI Evaluation: Support the financial appraisal, scenario planning, and business case framework for major new strategic initiatives, product launches, and capital deployment.

Architecture, Financial Modelling & Budgeting

• P&L & Forecast: Support business leaders and the FP&A team in preparing rolling forecasts and annual budgets, ensuring alignment with business priorities.
• Driver-Based Forecasting: Build and optimize dynamic financial models that clearly link non-financial operational drivers (e.g., traffic, CPM, CPC, etc) directly to financial outcomes (revenue, margin, cash).

• Strong in financial analysis, large datasets, Excel, and financial modelling.
• Able to explain complex financial topics clearly to non-financial stakeholders and work across functions.
